TB-16P8R
16 Opto-Isolated Inputs & 8 Relay Outputs
Termination Board
12 V and 24 V Coil Voltage Available !


Description

The TB-16P8R provides 16 opto-isolated digital inputs and 8 SPDT relay outputs. Each digital input accepts from 3 VDC to 24 VDC or 6.3 mA to 50 mA by changing a current limiting resistor. Its opto-isolated inputs provide both isolation between separate channels and between each input channel and your PC system.

On board 8 relay outputs are driven by an 8-bit digital output port. Each relay's switching capacity is 60 W / 125 VAC. The normally closed, normally open and common contacts of each relay are brought out via screw terminals to maximize its flexibility.

Both isolated inputs and relay outputs are equipped with LED's that light up when relays are energized or input signals are at "High" status
